Subject: Method for resetting embedded controller?
Date: Thu, 09 Oct 2003 14:06:16 +1300	[thread overview]
Message-ID: <1065661576.1807.7.camel@laptop-linux> (raw)

Hi.

I've been tracing the cause of keventd sometimes sucking all available
CPU after a suspend-to-disk (2.4.22). It seems that the embedded
controller in my Omnibook continally generates interrupts iif an ACPI
event occurs at the wrong time during the cycle (I haven't determined
when the critical time is yet). I'm therefore wondering if there is a
method whereby it can be reset or otherwise made to return to its normal
state.

I'm particularly noticing this when a lid event occurs during suspend,
whether or not button.o is insmod'd. If acpid is running, it shows
thousands of lid events per second. Another swsusp user has reported
similar issues.

Regards,

Nigel
